Application filed August 12, 1901. Serial No. 71,715. (No model.) f

To' all whom, it may concern:

Be itknown'that I, SAMUEL S. BaEoH IELa citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, haveinvented certain new and useful Improvements in Folding Stools, the same being a folding stool or seat that can also be used as a cane or walking-stick; and I do declare the following to be a full, clear, and exact description of the invention, such as'will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a partof this specification.

My invention has relation to improvements in folding stools or seats of that kind or style adapted to be folded so as to occupy a very small space diametrically andwhich may be extended and constitute a con venient, strong, and sightly stool.

It is the object to provide such a stool which maybe cheaply made, convenient in use, and easilycarriedin its collapsed or folded condition.

With these objects in view my invention consists in the novel construction of parts and their operative aggroupment-in combination, as will be hereinafter fully specified and particularly pointed out and distinctly.

claimed.

I have fully and clearly illustrated my improvements in the accompanying drawings, wherein- Figure 1 is a perspective view of my improved stool distended and ready for use.

Fig. 2 is a perspective view showing the stool as in folded position. Fig. 3 is a central transverse and vertical section through one of the collars enlarged. Fig. at is a central transverse vertical section through the middle collars enlarged. Fig. 5 is a detail View of one of the upper seat-rods and supporting-bars. Fig. 6 is a detail view of one of the lower bars and legs. Fig. 7 is a vertical central section through the supporting-standard, show-' ing the means for connecting the upper and lower parts. Fig. 8 is a detail view showing the means for holding the upper collar in position on the standard.

Referring to the drawings, A designates the supporting-standard, made of light tubustandard and there secured by suitable com entatiomor a pin 4 may be projected through the parts to accomplish the purpose. The rod 3 projects vertically to such a distance above the piece 2 as to provide a secure coupling with the piece 1, in which it slidingly'engages, as indicated in Fig. 7, and to prevent the part 1 from slipping off or down too far a notch 5 is formed in the coupling-rod, in which a pin 6 engages, as indicated. In order that the upper portion of the standard may be moved up and down onthe coupling-pin, that rod is cut away or flattened, as at 7, below the nose of the pin 6 to afford a passage for it in operating the standard to close and distend the frames of the stool.

8 9 designate collars placed at the top and bottom of the standard. These are duplicates in construction and consist of a metal ring adapted to fit over the standard at the points intended and are formed with radial recesses 10, extending partly the height of them, and an annular groove 11 in the walls between the recesses. The collar 8, being the upper one, is held rotatably and against vertical movement and displacement on the standard by any suitable means, as by a collar 1, upon which the collar 8 seats, and a nut 8, secured on the projecting end of the standard, while the collar 9 is fixed rigid on the lower end of the standard.

On the standard are slidingly mounted collars 10 ll .of similar general construction to the collars 8 and 9, but placed in reverse relation, as shown, with their plain ends and inner faces in closely-adjacent relation, and in these faces are formed coincident circular grooves forming a race 12, in which are placed antifriction-balls 13, so that the upper partof the stool is turnable or may be swung around by the person while seated thereon.

1 1 designates the seat arms or rods, having their inner ends seated in the recesses of the upper collar 8 and there pivotally held by a wire 15, lodged and secured in the annular groove 11, and of course passed through apertures in the seat-bars. The outer ends of the seat-bars 14: are pivotally secured to the up per ends of supporting-rods 16, having their lower ends disposed in the radial recesses 10 and there secured by a wire 17, passed through the supporting-rods and lodged and secured in the annular groove in the collar. In order that the middle or intermediate collars l0 and 11 may be held in proper relation and against separation when on the standard, a bushing b or sleeve is slidingly fitted on the standard and has its lower end fixed in the bore of the lower collar 11 and extended through the upper collar 10 in frictional contact, but so that the upper frame may be swung around on the hearing. The sliding collar 11 has the upper ends of the legs 18 pivotally connected in the radial recesses formed therein and secured by a wire passed through the ends and lodged in the annular groove, as in the other collars. These legs 18 have their lower ends curved inward, as at 19, and pivotally connected to the outer ends of radially-arranged bars 20, the inner ends of which are pivotally connected to the collar 9 at the foot of the standard, so that when the bars 20 are turned to horizontal position they form a base on which the whole structure is supported and rests, and also constitute the means which hold the legs in extended position, as shown in Fig. 1 of the drawings. It will be perceived that by reason of the curved-in ends of the legs the bars 20 when turned to verticality and folded will have room enough to lie between the standard and the inner face of the legs.

Over the seat-bars and suitably secured thereto and to the upper ends of the seat-supporting rods is atextile covering 21, forming the seat. This may be made of any suitable woven or other flexible material.

Constructed as described, the stool is made of light wires, yet of sufficient strength and rigidity to bear the weight which may be imposed upon it. It may under ordinary circumstances be folded so compactly that it will be in diameter not more than five-eighths of an inch, in which condition it may be incased in a tubular casing and carried by the hand or used as a cane, or it may be inclosed in a portfolio-case, or it may be packed in the seatpost or back frame of a bicycle, and for all purposes of outdoor recreation where little space and sufficient strength are the requisites the stool is handy and useful.

To set and utilize the stool for seating purposes, the standard is pushed downward, which movement acts to spread the seat-bars and push outward the upper ends of the supporting-bars and drawing up the intermediate collars, the legs being at the same time distended and the bottom bars caused to assume a horizontal position, as indicated in Fig. 1 of the drawings. To collapse or fold the frames, the upper portion of the standard is pulled upward to its limit, and then the lower part is treated in the same way, and the foldingis complete.

What I claim is 1. A folding'stool, comprising a two-part standard, a coupling-rod fixed in the lower part and slidingly engaged by the other part of the standard, radially-arranged seat-bars having their inner ends pivotally secured to the upper end of the standard, supportingbars having their upper ends secured to the outer ends of the seat-bars, a collar slidingly mounted on the standard intermediate the ends thereof and having the lower ends of the supporting-bars pivotally secured thereto, a second collar slidingly mounted on the stand ard and carrying the upper intermediate collar, legs pivotally connected to this second collar having their lower ends curved inward, bottom bars pivotally secured to the lowerend of the standard and their outer ends pivotally secured to the curved ends of the legs.

2. Afoldingstool comprisingavertical twopart standard, a coupling-pin rigidly secured in the upper end of the lower part and extending loosely Within the upper part, a collar rotatably mounted on the upper end of the standard and held against vertical displace ment, a collar rigidly fixed on the foot of the standard, collars slidingly mounted on the standard intermediate the ends, the upper one of the intermediate collars being rotatably mounted on the lower intermediate collar, seat-bars pivotally secured to the collar at the top of the standard, supporting-bars pivotally secured to the outer ends of the seat-barsan d having their lower ends pivotally secured to the upper intermediate collar, legs pivotally secured to the lower intermediate collar and having their lower ends curved inward and bottom bars having one end pivotally secured to the end of the curved portions of the legs and their inner ends pivotally secured to the collar on the lower end of the standard.

In testimony whereof I affix my signature in presence of two witnesses.
